+### File Server
+
+If using this on a machine serving multiple sites, 
+you'll need to add the configuration file to your existing Nginx setup. 
+Assign ownership of the directory to the `physics-workload-staff` group and add `nginx` to it:
+```bash 
+$ sudo usermod -a -G physics-workload-staff nginx
+$ sudo chgrp -R voidorchestra-staff /var/www/physics-workload
+$ sudo chmod -R g+rw /var/www/physics-workload 
+```
+
+Then, depending on your Linux distribution:
+
+#### Debian/Ubuntu
+Copy or link `nginx/physics-workload.conf` to your `/etc/nginx/sites-enabled/` directory, then restart Nginx:
+```bash
+$ ln -s /var/www/physics-workload/nginx/physics-workload.conf /etc/nginx/sites-enabled/ 
+$ sudo systemctl reload nginx
+$ sudo systemctl restart nginx
+```
+
+#### Fedora/RHEL
+Copy `nginx/physics-workload.conf` file to your `/etc/nginx/conf.d` directory.
+Then, flag the log directory as a log directory under SELinux,
+and the output directory as as HTML content directory too:
+```bash 
+$ sudo cp /var/www/voidorchestra/nginx/physics-workload.conf /etc/nginx/conf.d/ 
+$ sudo semanage fcontext -a -t httpd_sys_content_t "/var/www/physics-workload/staticfiles(/.*)?"
+$ sudo restorecon -R -v /var/www/physics-workload/staticfiles
+$ sudo semanage fcontext -a -t httpd_log_t "/var/www/physics-workload/logs(/.*)?"
+$ sudo restorecon -R -v /var/www/physics-workload/logs/
+```
